If your toothbrush is not responding and not charging at all, it means that the PCB or motor of the toothbrush is damaged and replacing the batteries will not help. This is due to the deterioration of the rubber seal which allows water to seep into the handle and further damage the internal structure.（We recommend that you replace the rubber seal every 3 months）
